This paper describes an application of classroom technology in support of teaching through the use of examples and active learning techniques. Here we report on using Classroom Presenter, a Tablet PC based classroom interaction system, in a senior level course in Algorithms -a domain for which the instructor believes working on sample problems is critical to student learning in the classroom. The role of the technology was to integrate activities into the lecture so that students have the opportunity to work with concrete examples in class, while the instructor can collect and review student work in real time, incorporating selected student answers into the discussion. In this paper, we describe the pedagogical goals of the instructor, the types of activities used to achieve those goals, and the role that technology played in supporting those goals and activities. The contributions of the paper are in showing how classroom technology can be used to support pedagogical choices, as well as in emphasizing the value of having clear pedagogical goals when incorporating a new technology in the classroom. We believe the application of technology as illustrated in this work could bring similar benefits to the instruction in other disciplines.

Abstract. Active Learning in the classroom domain presents an interesting case for integrating physical and digital affordances. Traditional physical handouts and transparencies are giving way to new digital slides and PCs, but the fully digital systems still lag behind the physical artifacts in many aspects such as readability and tangibility. To better understand the interplay between physical and digital affordances in this domain, we developed PaperCP, a paper-based interface for a Tablet PC-based classroom interaction system (Classroom Presenter), and deployed it in an actual university course. This paper reports on an exploratory experiment studying the use of the system in a real-world scenario. The experiment confirms the feasibility of the paper interface in supporting student-instructor communication for Active Learning. We also discuss the challenges associated with creating a physical interface such as print layout, the use of pen gestures, and logistical issues.
